Record 1 (the newest record) will always be displayed first whenever you press the R button to switch from the
Stopwatch Mode to the Recall Mode.
In the Recall Mode, each press of the B button will toggle the display between record group 1 and record group
2.
Lap time records in memory can be recalled while an elapsed time operation is in progress or stopped.
Memory records are cleared whenever a new Stopwatch Mode elapsed time operation is stared by pressing the
C button after pressing the A button to reset the stopwatch to all zeros.
